HTN Attorney's failure to register employees

I'm very angry with HTN Attorney's. I was an employee at HTN Attorney's in which we were told to sign documents that moves us to a company under them called Trigger. My contract ended on the 06 December 2021. I asked for my UI 19 forms and salary schedule from Daniel and Andre of HR via email more than 4 times and they did not reply. Only to find out after multiple attempts of contacting them via labour, I learnt that I was not registered by HTN Attorney's nor Trigger their lead gen company. All I need is my UI 19 forms and salary schedule
